"Weight is a major concern for those who buy a laptop. Since it's supposed to be carried around, it has to be as lightweight as possible. Most people don't realize however that heat is also an issue. Notebooks have a tendency to get really hot during prolonged usage. There are several cooling solutions on the market, most of them USB-powered fan units that are both heavy and noisy. iXoft, a new product from Thermaltake, is neither, relying on simple chemistry to cool a laptop and prevent the user from feeling its heat."
